How much compression does it have? When you slowly pull on the starter cord, does the truck lift up at all or is the pullstarter really easy to pull?

Have you checked that the head is on tight, try gently tightening the head bolts a little bit.

When it dies when you hit the throttle, does it sound gluggy and sluggish or does it just die cleanly and quickly?

some times it pulls with no force,next time it pulls good and starts,sometimes the whole truck comes up with it.

now for when i give it throttle and it dies,starts to go and goes clunk,almost everytime.

Looks like you have a Ofna LX series buggy there. Those tires will KILL your clutch with the stock gearing. That may be your problem. Have you looked at it yet? pull the motor and see if the clutch bell spins freely. If not it may be the clutch or clutch bearings, or both. You will need to remove the bolt that holds the cb(clutch bell) on. This can be a pain, if you cantget it off, report back!

It may be time for new bearings, be careful there are shims between them. What kind of clutch do you have? is it silver aluw,blue alum, or a black carbon? The inside of the bell should be smooth, not grooved. If its alum there should be no burrs on it, also if its worn down to the springs(metal springs that hold them on) its time for new ones.

NOW on to what you have(what I think you have),I had this same thing, a Ofna buggy that someone put big ole' MT tires on. it was SLOW off the line and turned like crap. It will EAT clutches like this, b/c it puts a huge strain on the clutch. Also, I think that is the WRONG pipe for that motor, it looks like a CEVC 1/10 pipe, you need a 1/8 pipe. Any from a 1/8 will work, you can pick a stock RTR pipe off of ebay for CHEAP.

Here is some decent reading.....

I regeared my buggy for MT tires, used wheel extenders, and a few other things.

OK, when you pull the trigger it just dies? Try to have the wheels off of the ground(have a friend hold it pipe AWAY from them!), and SLOWLY pull the trigger. its called "clearing it out". You dont have to go wide open the 1st time clearing it. but you should be able to the 2nd or 3rd time.
